Hi jhon,

thank you.

finaly i found a javascript that replace a text box to a checkbox in textarray question :


<script type="text/javascript" charset="utf-8">

$(document).ready(function(){

// Identify this question
var thisQuestion = $('#question{QID}');

// Assign column-specific classes
$('table.subquestion-list tr', thisQuestion).each(function(i) {

$('> *:gt(0)', this).each(function(i){
$(this).addClass('column-'+(i+1));
$(this).attr('data-column', i+1);
});
});

// Hide the text inputs in columns 1 and 4
$('.column-1 input[type="text"]', thisQuestion).hide();






// Insert the checkboxes into column 1
$('.answer-item.column-1').append('<input class="checkbox inserted-checkbox" type="checkbox" />');

// Initial checkbox states (if the question has already been answered)
$('.answer-item.column-1 input[type="text"]').each(function(i){
if($.trim($(this).val()) == 'Y') {
$(this).closest('td').find('.inserted-checkbox').attr('checked', true);
}
});

// Listener on the checkboxes (insert "Y" into hidden text input when checked)
$('.inserted-checkbox').change(function() {
if($(this).is(':checked')) {
$(this).closest('td').find('input[type="text"]').val('Y');
}
else {
$(this).closest('td').find('input[type="text"]').val('');
}
});
});
</script>

it's work gread, now just looking to center the checkbox
